> An excerpt from a plugin's dependency tree

> [INFO] org.apache.maven.plugins:maven-resources-plugin:maven-plugin:2.2
> [INFO] +- org.apache.maven:maven-plugin-api:jar:2.0:compile
> [INFO] +- org.apache.maven:maven-project:jar:2.0:compile
> [INFO] | +- org.codehaus.plexus:plexus-utils:jar:1.0.4:compile
> {noformat}
> Note that the plugin has an indirect dependency on plexus-utils:1.0.4 via
> maven-project.
> Maven curently filters out core artifacts and their transitive dependencies
> from the plugin realm. Given the above example, this also removes
> plexus-utils from the plugin artifacts. Maven 2.x injects plexus-utils:1.1
> instead, Maven 3.x injects the plexus-utils from its distro. In both cases,
> the plugin ends up with a different version of plexus-utils than it was
> compiled/tested with, giving rise to linkage errors or wrong plugin behavior.
> The issue is theoretically not limited to plexus-utils but it's the most
> prominent example.
